This disease may result in inadequate blood flow to the myocardium, or myocardial ischemia, which is typically responsible for complications such as angina pectoris, necrosis of cardiac tissue (myocardial infarction), and sudden death.
In more severe cases, coronary bypass surgery may be required when other methods of treatment are impossible for a variety of reasons or ineffective in clearing the occluded artery.
Such an incision can result in severe post oper

DETAILED DESCRIPTION OF THE DRAWINGS AND THE PRESENTLY PREFERRED EMBODIMENTS

[0019]For the purposes of promoting an understanding of the principles of the present disclosure, reference will now be made to the embodiments illustrated in the drawings, and specific language will be used to describe the same.

[0020]In the following discussion, the terms “proximal” and “distal” will be used to describe the opposing axial ends of the inventive instrument, as well as the axial ends of various component features. The term “proximal” is used in its conventional sense to refer to the end of the instrument (or component thereof) that is closest to the operator during use of the instrument. The term “distal” is used in its conventional sense to refer to the end of the instrument (or component thereof) that is initially inserted into the patient, or that is closest to the patient during use.

[0021]Generally speaking, the present disclosure is directed to a surgical instrument. The instrument may b...

Abstract

A surgical instrument and a method for using the instrument are provided. The instrument can include a tubular member. A grasper can extend within the tubular member. The grasper can have grasping members each with a distal body. An opening can be formed in an inner surface of each distal body. The grasping members can pivot between an open and a closed configuration to engage a body vessel or tissue. A cutting device can extend within the tubular member. The cutting device can have a cutting member with a cutting edge. The cutting member can be movable between a free and an engaged configuration to sever a body vessel or tissue. When the grasping members are in the closed configuration, the openings of the distal bodies can form a cavity to receive the cutting member to shield the cutting member during navigation within a body of a patient.

Description

TECHNICAL FIELD [0001]The present disclosure relates generally to medical devices and methods of use. More particularly, it relates to surgical instruments, such as endoscopic or laparoscopic instruments, for removing body tissue or vessels, such as saphenous veins for use in coronary artery bypass surgery.BACKGROUND [0002]Coronary artery disease is often characterized by lesions or occlusions in the coronary arteries. This disease may result in inadequate blood flow to the myocardium, or myocardial ischemia, which is typically responsible for complications such as angina pectoris, necrosis of cardiac tissue (myocardial infarction), and sudden death. Drugs and / or modifications in behavior and diet may be used to treat coronary artery disease. Other types of treatment include dilation of coronary arteries by procedures such as angioplasty, laser ablation, atherectomy, catheterization, and implantation of intravascular stents. In more severe cases, coronary bypass surgery may be requi...
